Good to know

• Your log never leaves the browser — parsing and charting happen 100% on-device, nothing is uploaded.
• Excel files (.xlsx/.xls) are supported: the first worksheet is read, with the header row detected automatically.
• Delimiters are auto-detected (comma, semicolon or tab) and the time column is guessed — change the X axis picker if needed.
• Big logs are fine: up to 25 MB / 200,000 rows, drawn with LTTB sampling so zooming stays smooth.
• A 10 Hz log over a full track session can be enormous — select only the channels you need to keep the chart readable.
• Saving a log to your vehicle’s history in the Garage is on the roadmap.
